What causes ejaculatory duct obstruction?

What causes ejaculatory duct obstruction?

Causes of EDO include:

• Genes, like those involved in cystic fibrosis, cause a structural difference that you’re born with. For instance, the ducts may be absent (atresia) or atrophic (collapsed).
• Scar tissue from previous pelvic surgery or damage to the urethra.
• Stones (also called calculi).
• Cysts.
• Previous frequent urinary tract infections (UTIs).
• Prostatitis that is chronic (lasts for a long time).
• Epididymitis (inflammation of the epididymis, the cord that transports sperm located at the back of each testis).

Issues with the seminal vesicle may seem to be a blockage in your ejaculatory ducts.
